GiroDisc 2020 Subaru WRX (w/Brembo Calipers Performance Pkg) Slotted Rear Rings

These GiroDisc rear rotor rings are made from a high-carbon iron alloy, a material chosen for its ability to handle the heat generated during hard braking. They are designed to replace the original cast iron rotor rings on your 2020 Subaru WRX equipped with the Brembo Performance Package calipers. The key feature here is the slotting pattern, which is specifically engineered to help vent gases and heat away from the braking surface. This helps maintain consistent stopping power, especially during repeated hard stops or track use, preventing the glazing and fade that can occur with standard rotors.

GiroDisc uses a unique mounting hat design that allows the rotor ring to expand and contract freely with temperature changes. This floating design helps prevent the rotor from cracking under extreme thermal stress, a common issue with fixed-hat rotors on high-performance vehicles. The rings themselves are precision-machined with a specific slot pattern that not only aids in heat dissipation but also helps to sweep away dust and debris from the brake pads. This combination of advanced materials and thoughtful design means you get improved braking performance and longer rotor life compared to stock components.

When installing these rotor rings, you'll be reusing your existing brake caliper mounting brackets. The package includes the two rotor rings needed for the rear axle. Make sure to follow the manufacturer's instructions for proper installation and bedding-in procedures to get the most out of your new GiroDisc rotors.
